I have a Dell Dimension 9200 that has a 8600GTS graphic card. I've been happy with it overall as I can still play games at decent settings. However the card is starting to crap out on me and I feel it's life is almost over. Hence I'm looking for a new card for when it does die on me.
The computer has from the documentation a 375w power supply but going on dell site it says 300w so I'm not sure which one is accurate or not (doesn't really matter cause cards are either 300 or 400w it seems).
So knowing this looking at what is on the market the only two I could find were:
Nvidia GT 430 and GT 520
It's hard to find a good performance comparison between some of the older cards hence if there is another model - let it be nvidia or ati that would work on my computer please let me know.
What are your thoughts on these two cards keeping in mind my computer realities.
